Application filedFebruaiy 26,1919. serial No. $19312.

To all whom it may 00mm: i q j Be it known that Ll VILLIAM SGHERER,

a citizen of the United States of America,

residing at Nestomin thecounty of Campbell and State of Wyoming, have invented new and usefulImprovements in Rallroad- Ties, of which the following is a specification.

As its principal object, the invention seeks to provide a metallic railroad tie of hollow construction and semicircular conformation in cross section, so that the tie proper may act as a covering for a concrete supporting medium which it is intended shall becontained in the hollow portion.

A further object of the invention resides in the provision of unique and eflicient rail attaching means whereby the rails are effectively secured to the tie by clamping members which do not have to be bolted thereto.

Still further and other objects appear hereinafter as the invention is set forth in detail.

As shown and described, a specific embodiment of the invention is adhered to but to this embodiment the invention is not to be restricted. The actual reduction to practice may suggest certain desirable changes or alterations and the right is reserved to make any which do not deviate from the scope of the annexed claims.

In the accompanying drawings:

Figure 1 is a top plan View of the improved tie showing the positions of the rails attached thereto.

Fig. 2 is a front elevational structure shown in Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. i

Fig. 4 is a section on the line 4E-l of Fig. 1.

Fig. 5 is a transverse sectional view of the tie looking at the inside of the rail.

Fig. 6 is a perspective view of the detachable rail securing clamp.

Fig. 7 is a perspective view of the clamping dog. I

As shown, the invention comprises a tie body 1 which is of hollow construction as shown and of semicircular conformation in cross section. On top ofthe tie and for a specified length from either end and on either side of the transverse center there are view of the formed the V-shaped recesses 22, so that there is left a rib 3 of theshape of a trapezium in cross section, the top face of the tie being formed fiat to leave the upper or larger base of the trapezoidalconformation. Atthc inner endof the rib 3, the top face of theftie is undercut toleavethe rail'base engaging projection a and the base of the rail5, on one side isoverhung and engagedby this pro ectlon. The opposite s de of the base of therail 5 is overhung andengaged by the flange 6 of the clamping member 7, this member being of greater length than the width of therib 3, so that the dove tail slot 8 may be formed in its under face, this dove tail slot providing means to permit the clamping member to be slidably engageable over the rib 3. But at its longitudinal center, and 'on the side opposite the flange 6, the clamping member has a recess 9 formed therein, this recess being for the reception of the nose 10 of thelocking dog 11.

The rib 3 adjacent to the end of the tie is formed with a transverse dove tail slot 12 and the rib is furtherformed with a depression 13 adjacent the dove tail slot 12, this depression receiving the heel 14: of the locking dog, the tongue 15 of which rests in a second depression 16 formed in the bottom of the dove tail slot, so that the top of the tongue will lie flush with the bottom of the said slot.

Thisdove tail slot is designed to receive the V-shaped looking wedge 17, the bottom of which, when the wedge concerned, rests upon the tongue 15 and secures the locking dog in-place, the nose of the locking dog engaging in the recess 9 of the clamping 1nemher 7 and thus serving to hold it in firm engagement with the rail 6. The locking dog and the wedge thus serve to secure the j the use of. the latter it is purposed to fill the hollow interior space with concrete, thus providing a tie capable of resisting all compressive strain.

The invention having been described what is claimed as new and useful is: w The combination with a tie having in verted. trapezoidal shaped ribs formed on its upper face adjacent its ends, of clamping members slotted on their underface for slidable engagement with said ribs, the clamping dogs, the locking dogs being formed with tongues and the ribs having further depressions to receive the said tongues, and V- shapedwedges carried in the dove tail slots the bottoms of which coincide with the tops of the depressions, whereby the wedges are adapted to lock in the tongues in said depressions. V i

2. The comblnatlon with a tiehavlng 111- verted trapezoidal-shaped ribs formed on its upper face adjacent its ends, of clamping members slotted on their undert'ace for slidable engagement with said ribs, the clamping members and the tie both having rail base engaging means, 10ckin dogs having one end engageable with the c ainping members, and V-shaped wedges insertible in slots formed transversely across the tie, the said wedges engaging the locking dogs to maintain 'the latter in engagement with the clamping members.

In testimony whereof I aifix my signature.
